Class XPathClassificationFilter

java.lang.Object
oracle.irm.engine.types.core.classification.ClassificationFilter
oracle.irm.engine.types.core.classification.XPathClassificationFilter

All Implemented Interfaces:

Serializable

public class XPathClassificationFilter

extends ClassificationFilter

implements Serializable

X Path Classification Filter type. An XPath classification filter uses a boolean XPath expression to filter out applicable classifications. The classification Cookie is transformed into an XML document and then compared against the boolean XPath expression. This can be used as a generic way of filtering out Classification instances by running an expression against the XML based cookie.

For example, the context classification system uses an XPath that matches on the Context UUID. e.g. the following XPath expression would match all sealed content that had a context cookie with a context UUID of 37bbe0fa-9eb4-462e-85b6-9796610f1b20.

context:ContextCookie/context[uuid='37bbe0fa-9eb4-462e-85b6-9796610f1b20'].

XML Serialization

X Path Classification Filter instances can be serialized as an XML document. This XML document can also be used to recreate a X Path Classification Filter object. The following XML document shows an example X Path Classification Filter in XML form.

<?xml version="1.0" encoding="UTF-8"?>
<core:XPathClassificationFilter xmlns:core="http://xmlns.oracle.com/irm/core">
<system>
<uuid>185abb6d-13cd-45a2-aabd-4db886b97c5c</uuid>
</system>
<uri>http://irm.example.com/irm_desktop</uri>
<index>value</index>
<expression>
<namespaceContexts xmlns:example1="http://www.example.com">example1:example</namespaceContexts>
<namespaceContexts xmlns:example2="http://www.example2.com">example2:example</namespaceContexts>
<value>example1:node[@name='value']</value>
</expression>
</core:XPathClassificationFilter>
